This paper presents a study of the physical limitations for radio frequency absorption in gold nanoparticle (GNP) suspensions. A spherical geometry is considered consisting of a spherical suspension of colloidal GNPs characterized as an arbitrary passive dielectric material which is immersed in an arbitrary lossy medium. A relative heating coefficient and a corresponding optimal near field excitation are defined, taking the skin effect of the surrounding medium into account. The classical Mie…

A new simplified formula is derived for the absorption cross section of small dielectric ellipsoidal particles embedded in lossy media. The new expression leads directly to a closed form solution for

Differential heating of metal nanostructures by radio frequencies: a theoretical study

While spherical metallic nanoparticles do not offer differential heating in tissue, large absorption cross sections can be obtained from long prolate spheroids, while thin oblateSpheroids offer minor potential for absorption, suggesting that metallic nanowires should be considered for RF- and microwave-based wireless hyperthermia treatments in many tissues going forward.

This paper reformulates and extends some recent analytical results concerning a new optical theorem and the associated physical bounds on absorption in lossy media. The analysis is valid for any

Study of absorption of radio frequency field by gold nanoparticles and nanoclusters in biological medium

A systematic study of the absorption of capacitive RF field by AuNPs and AuNCs dispersed in phosphate-buffered saline (PBS) is reported here in tissue mimicking phantom, and it is concluded that AuNps and Au NCs do not enhance theabsor of RF-capacitive field and power absorption observed in the biological medium is due to the ions present in the medium.

Optical theorems and physical bounds on absorption in lossy media.

Two different versions of an optical theorem for a scattering body embedded inside a lossy background medium are derived and a new fundamental upper bound on the total absorption of an inclusion with an arbitrary material property is given.

We report on the absorption of electromagnetic radiation by metallic nanoparticles in the radio and far infrared frequency range, and subsequent heating of nanoparticle solutions. A recent series of

Low frequency heating of gold nanoparticle dispersions for non-invasive thermal therapies.

None of the established theories supports the idea that GNPs can dissipate RF energy significantly, and the measured dielectric properties of GNP dispersions show a negligible change in the effective conductivities for purified samples, which indicates that the dielectrics loss alone does not predict substantial temperature increase of GNPs.

An investigation of the impedance properties of gold nanoparticles

The property of nanoparticles the authors wish to explore and characterise is impedance, which is well known to be highly conductive and could be highly effective as a contrast agent for electrical impedance tomography, particularly when combined with tumour targeting.
